vTo all whom it concern:

Be it known that I, BUR'r A. PETERSON, a

citizen of the United States, residing at.

Rockford, in the county of lVinnebago and State of Illinois, haveinvented certain new and useful Improvements in Knotters, of

, which the' following is a specication.

Thisw invention' relates to a means Afor forming knots, and its objectis to simplify'v the means for tightening the knot and vre- -is aragmenta transverse vertical .section through a warp-tying machineprovided with a knotter embodying my invention. Fig. 2 i

is a front elevation of said knotter. Fig. is

. a sectional view taken on the plane of dotted removable bill Vspringin place.

line 3 3 of Fi 2. Fig. l yis a side view of the knotter looking from theright of Fig. 2. Figs. 5, 6, 7, 8 and 9 are views, in a Series,illustrating the operation of tying a knot as performed by thisknetter." Fig. 10 isa diagrammatic view of the knot formed. Fig. 11 1s aside view of the tying bill, showing in longitudinal central section theCanrbarrel that actuates the movable shearing and clamping jaw of saidbill. Fig. 12 is an npper end view of said cam barrel. Fig. 1? is a.transverse section through the knetter shaft, illustrating the sleevefor .securing the l Fig. 14 is a 1an View showing t-he relativepositions e knot-t ing mechanism and a means for drawing t e knottedthreads clear of said said devices.

AI have herein illustrated my invention as comprised in a warp-tyingmachine ot" the vgeneral form shown in British Patent No. 10,484 of1904, to Howard l). Colman, to which patent. reference may be had for afull understanding of the relation ot the knotter mechanism. Fig. 15 isa side elevation of lto the other mechanisms of the machine.

The machine may be briefly vdescribed as comprising a bed havingthcreontwo stationary thread clamps, and a warp carriage located above saidbcd, said carriage also being provided withl a pair of thread clamps.

-The cla mps upon the bed arefor holding one of the warps to be operatedupon, and the clamps on the carriage are intended for the other warp.Upon the bed is mounted a carriage (hereinafter called the maincarriage) arranged to travel transversely of the warp threads, and fromone side of the narps to the other, said main carriage supporting aknetter, mechanism for selecting warp threads in pairs, one from cachwarp7 and mechanism for bringing each selected pair of threads intooperative relation with said knotter. Y

In Fig. 1 the reference numerals 1 and 2 indicate stationary threadclamps upon the bed (not shown) of the'warp-tying machine. 3 and 4 arethread clamps carried by the warp carriage. and 6 are metallic ribbonsor blades havino' serrated ed es over which the `war threads extend,said ribbons beingcarried. y the bed and the warp carriage,respectively;v The Wal-ps are indicated' in Fig. 1 by the referenceletters a and b. Upon-the bed of the machine, betweenl the clamps 1 and2, is mounted a main carf ria'ge (not herein shown) supporting thedevices (also not shown) for ,selecting threads from the warps a and L;reciprocatory separator blades 71 and 8'.:tor separating theselected'threads from adjacent or following threads, Said blades havingforks (not shown) between them for causing said threads to be moved'toward each other as said blades and forks advance the threads to theknotter 9; a reciprocatory shear blade 10 adapted to coact with arelatively stationary shear blade 11 for' severing the sclected threadsto provide loose ends for the knot-forming operation; a'suction air-tubel2 for holding the severed ends of the threads; a thread guide 4l; and areciprocatory fork 42 for removing the united warp threads from theknetter. A

" The knottcr t) comprises a knottcr frame 13 rigidly mounted upon themain carriage.

Saidl knetter frame comprises bearings 14v Upon one end of said shaft isfixed a lO-i A spiral gear 18 rigidly mounted upon pinion 19 iixcd upona knotter shaft .20, said Shaft being rotatably supported in bearings 2land 22 in the knetter frame 13. A cambarrel 23 `is rigidly mounted inthe knotter frame, said barrel being open at its upper end and having abearing opening 24 in its lower end through which the knotter shaft 20extends. As shown in Figs. 2,- 11, and 12, the bearing opening 24 iseccentric with relation to said cam-barrel, and said barrel has aninterior cam 'conformation substantially of heart-shape incross-section. lVithin the cam-barrel and toward its upper endthe'knotter shaft 2O is flattened, and at its upper endsaid shaft isbent in a plane with its flattened surface at an angle somewhat reaterthan a right angle to form the tying ill 25. At its bend and upon itsflattened side the knottery shaft 20 is provided with a pivot pin 26 fora shearing and clamping Jaw to be hereinafter described, said jaw l lngbetween the knotter shaft 20 anda b1ll s ring 27 secured in lace bymeans of a s eeve 28 (Figs. 11 and) 12) fixed upon Said knotter shaft.The point of the bill sprin 27 is bent to correspond with the shape othe tying bill 25, and said bill sprin is perforated to receivethe outerend of t e pivot pin 26. A shearing and clamping jaw 29, pivotallymounted upon the pin 26, has a point 30 corres ondlng in form with thetyin -bill 25 an a cam-wing 31 lying within t e cam-barrel 23. When theshaft 20 is rotated the shearing and clamping jaw 29 is moved upon itspivot 26 by reason of the cam conformation and the eccentricity of thecam-barrel 23.l 'The edge ofthe shearing and clamping jaw adjacent tothe bill spring 27'is shar ened to form a thread shear with said bilspring, whilethe other side of the point of sald jaw forms a threadlflalmp with the flattened side of the tying In the bracket 32 of theknotter frame 13A riphery. In the` present embodiment the earing forrotating the tying bill 25 and t e strlpper disk 36 is so proportionedas'rto cause two revolutions of the tyin bill to one of the stri perdisk. A bla e l38, in this instance ormed integral with the bracket 32,is located between the tying bill 25 and the stripper disk 36. At theouter side of the stripper disk 36'is a uide 39 having a notch 40therein,ksaid gui e being rigidly secured to the knotter frame 13. T eupper edge of the blade 38, the peripheral ed es of the disk 36, and theu per ed es 0% the guide 39 are roundedat both si es to prevent wear orbreakage-of the threads extending thereover.

In `the operation of the warp-t ing machine, two threads, one from eacof the warps a and Z), are selected, separated from adjacent 0r adheringthreads,v and severed by the shear blades 10 and 11. The free ends thusformed of the threads are drawn into the suction air-tube 12 and saidthreads brought close together and substantially parallel, and advancedto a position within the circle described `by the point of the tyingbill 25 in its rotation, as shown in Fig. 5. In the initial position ofthe tying mechanism the tying bill v25 extends forwardl frointhe knottershaft 20. 'whilethe'hook 37 of the stripper disk 36 is at the point inits path substantially farthest from said bill. The first three-fourthsof a revolution of the tying bill winds the threads about the knottershaft 20. At this time the shearing and clamping jaw 29 is opened byreason Vof the eccentricity of the cambarrel 23, gl'asps the twothreads, and shears and clamps them. threads are drawn into the suctionair-tube 12 and removed. The stripper disk 36 meanwhile has been rotatedinto osition for the hook .37 to engage the threa s, and, as anadditional one-third revolution of the t ing bill occurs, said stripperdisk draws the threads downward. between the blade 38 and the notchedguide 39, tightening the knot andstripping it from the tying bill. AtAthis point the'reciprocatory fork 42 is actuated to draw` t-he threadsaway from said strip er disk and said guide. The completion o thesecond.revolution of the tying bill 25 finds it in the initial positionreadythev meantime has been placed in operativle position. In case thethread-selecting devices fail to select aV thread from each warp,

the separator blades 7 and 8 and the fork 42 will (by .mechanism notherein shown) be arrested before they have completed their The wasteends of the.

to engagefanother pair of threads, which in full forward movement,therefore the fork 42 will not `advance far enough to remove the lastprevious knot from the knot-tying lmechanism. As the stripper disk 36continues its rotation after pulling said knot from the tying bill, Saiddisk Wipes the knotted end of the threads downward into the spacebetween said disk and the guide -39, as indicated in dotted lineinFig.15.`

The knotted thread ends will remain in this posit-ion until the fork 42makes a full forwardmovement and pulls said thread ends into theposition shown in Fi 14. It will therefore be seen that shoul the fork42 be arrested and consequently fail to draw the knotted ends clear ofthe knot-tying mechanism immediately after the knot is completed, saidends will be well within the v orbit of the hook 37 and in no danger ofbeing caught and broken by said hook 37.
